Event processing conflicts on tree drag drop

[cagataycivici]

This is reported by a PRO user;

I have requirement to display the data in a tree with drag and drop functionality to move the leaf nodes from one folder to another folder in a tree. As per the requirement I can have only one root node which will have the complete tree below it.
Root-----------------------------------------
------ A ------------------------------------
------ XX(Folder)----------------------------
------------------- B------------------------
------ YY(Folder)----------------------------
-------------------- C-----------------------
--------------------ZZ(Empty Folder)-------
-------------------- D-----------------------
Problem Statement:
While dragging and dropping the tree node from one folder to another folder, the folder name is changed to the name of the folder from where it is dragged from. e.g. If you see in the above tree If I try to drag the last node "D" from "YY" folder to between "A" node and "XX" folder then the "XX" folder name is changed to "YY".
